Like automakers everywhere, BMW is being squeezed by environmental issues (carbon-dioxide emissions, for one) and the need to improve the fuel economy of its fleet. What does this mean for the German automaker’s power-focused M division, with its fuel-hungry road gobblers? We recently asked Ludwig Willisch, who heads the division.
Willisch told us that the next generation of M engines will have smaller displacement, which could mean less power. But turbocharging will help mitigate the decrease in displacement and should keep power levels about where they are today. And should the output drop, future products will lose pounds to maintain the power-to-weight ratios of today’s M products. Willisch even mentioned deleting somewhat heavy options such as power seats. Here’s what to expect from the M division in the next few years:
2009: M models of the X5 and X6 arrive this fall with an uprated version of BMW’s twin-turbocharged 4.4-liter V-8 that bristles with 21 psi of boost, 555 horsepower, and 500 pound-feet of torque at a low 1500 rpm. A new launch-control function enables ridiculous 0-to-60 times in the low fours.
2012: Willisch told us the M5 and M6 will have an engine that is similar in concept to the X5/X6 M but not the same—maybe a small-displacement twin-turbo V-8 or even a radical twin-turbo V-6.
2014: An M version of the next-gen 1-series may arrive powered by a twin-turbo inline-four. BMW is looking at the business case before any engineering plans are made, but the goal would be about 300 horsepower with a 2900-pound curb weight.
2015: The next M3 will be the “best” M3 ever and faster than today’s car, said Willisch. Work on the future M3 hasn’t begun, but an inline-six and a V-6 are both being considered. Expect E30-like levels of mayhem.
